WHEEL-CULTIVATOR.

QPECIFICATION forming part of Letters Patent No. 315,277, dated April 7, 1885.

' Application the December 3, 1884. (No model.)

To all whom it may concern;

Be it known that I, FRANK HAMMERS, a citizen of the United States, residing at Hebron, in the county of Adair and State of Iowa, have invented certain new and useful Improvements in Wheel-Cultivators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a plan view of a wheel-cultivator embodying my improvements. Fig. 2 isa side elevation of same. Fig. 3 is a front View; and Figs. 4 and 5 are details to be referred to.

Similar letters of reference indicate corre sponding parts in the several figures.

My invention relates to wheel-cultivators; and it consists in the peculiar arrangement, construction, and combination of devices, all of which I shall hereinafter fully set forth and specifically claim.

To enable others skilled in the art to make and use my invention, I will now proceed to describe the exact manner in which I have carried it out.

In the said drawings, A A represent the supporting-wheels of the cultivator, which are mounted upon the short shafts a, and B B are the plow-beams.

0 represents a curved arch-piece located at the front of the cultivator, and provided with suitable means for supporting the tongue and forward ends of the beams B. This arch is constructed, preferably, in the form shown in Fig. 3, and is provided on its upper surface with an upwardly-extending bolt, 12, which passes through the tongue D and serves as a pivot upon which the tongue turns, while a nut secures the parts together. The lower ends of the arch O are made wide, and are bent at right angles to the vertical plane of the arch, as shown, and these ends are slotted to form arms 0 0, between which the forward ends of the plow-beams are secured by means of blocks d, pivotally secured between flanges 'e, secured to the beams proper and extending outwardly, so as to encompass the blocks on their inner ends, but at the same time form such a connection that will effectually prevent any side movement of the beams, except such as is derived through the bolts f, which pass through the arms 0 and blocks d. The arms 0 c are formed with two or more perforations, which, with bolts f, permit the beams to be adjusted, thereby regulating the distance between the forward end of the beams. the extreme outer ends of the. arms 0 are formed additional perforations, 6, through which pass the rods E, upon which are formed shoulders 3, between which and the upper arm, 0, are placed short hollow spindles 5, while the the arms 0, are constructed so as to extend both rearwardly and forwardly, the rear portions being bent at 6 to form the short shafts mounted. The forward ends of the rods E are simply a continuation of the rear and main portions of the rods, and they have curved outer ends or eyes, It, to which may be attached single-trees when it is desired to a tongueless cultivator. it

Upon the arch-piece G is bolted a curved bar,'F, which passes through aloop, i, and serves as a fifth-wheel upon which the tongue D turns. Upon the rear end of the tongue is pivotally secured a cross-bar, G, having perforations in each end, through which pass the upper bent ends of the rods E, having threadto the cross-bar, and by this construction impart its movement to the rods, to assistthe action of the wheels A in turning the cultivator around.

Secured to the tongue just in front of the each end the connecting-bars I, to which is secured the single-trees J, the lower ends of the bars I being secured to the hooks h.

I will now proceed to describe the cultivator teeth and cutters and their peculiar construction and attachment.

Upon the rear end of beams B and upon each side are secured the standards K and L, the former carrying the ordinary cultivatorteeth, while a brace, Z, having a bifurcated end a construction similar to that just referred to; but instead of cultivator-teeth these standards have secured to them, through the medium of bent irons 0, one end of the diagoed ends to receive nuts which secure the rodswhich engages a bar, m, is secured to the standard K. The standards L and braces n are of 100 lower ends of the rods E, afterpassing through or, upon which the supporting-wheels are convert the cultivator into what is known as arch G is a cross-bar, H, having attached at tached to the rear of standards K, keeps the rear ends of the beam in the same relative position in whatever position the machine is placed.

P are suitable handles braced by the irons 10 9, secured to the beams B, and are adapted to engage hooks R, secured to the cross-beam G, and hold either one or both of the beams out of the ground, when desired, as in going from the field.

From the foregoing description it is evident that the cultivator can, by a simple change of mechanism, be made a limber-tongue cultivator, and can also be made a tongueless cultivator by removing the tongue, when attached to the arch, and placing the single-trees on the hooks attached to axle; and, also, that the scraper-shovels, by extending from the front to the hind post or standard, leaves no weeds uncut between these postsa feature greatly to be desired.

Having thus fully described my invention, desire to secure by What I claim as new, and Letters Patent, is-

1. In a wheel-cultivator, the combination, with the supporting-wheels, of the arch portion 0, having bifurcated lower ends, and the rods E, substantially as herein described.

2. In a cultivator, the Wheels A, beams B, and tongue D, in combination With the arch portion 0, having bifurcated ends in which are adjusted the blocks (1, the bars E, forming the shafts for the wheels, and also the means for attaching the single-trees, the curved bar F, secured to the portion 0, and the crossbar G, all constructed to operate substantially as described, and for the purpose herein set forth.

3. In a cultivator, the beams B, in combination with the standards K and L, the braces Z and n, with bifurcated ends engaging bars m, cultivator-teeth secured to the standards K, diagonally-placed knives or cutters connected to both standards, and a transverse bar, N, all constructed and arranged to operate as herein described.
